Evaluation of the Efficacy of Immune and Inflammatory Markers in the Diagnosis of Lacrimal-Gland Benign Lymphoepithelial Lesion

Abstract

This study retrospectively analyzes the immune and inflammatory indices of patients with lacrimal-gland benign lymphoepithelial lesion (LGBLEL) in order to screen out reference indices with higher diagnostic efficacy. The medical histories of patients whose diagnoses of LGBLEL and primary lacrimal prolapse were confirmed by pathology between August 2010 and August 2019 were collected. In the LGBLEL group, the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, rheumatoid factor (RF), and immunoglobulins G, G1, G2, and G4 (IgG, IgG1, IgG2, IgG4) were higher (p < 0.05) and the expression level of C3 was lower (p < 0.05) compared to the lacrimal-gland prolapse group. Multivariate logistic regression analysis showed that IgG4, IgG, and C3 were independent risk factors for predicting LGBLEL occurrence (p < 0.05). The area under the receiver operating characteristic (ROC) curve of the prediction model (IgG4+IgG+C3) was 0.926, which was significantly better than that of any single factor. Therefore, serum levels of IgG4, IgG, and C3 were independent risk factors for predicting the occurrence of LGBLEL, and the combined diagnostic efficacy of IgG4+IgG+C3 was the highest.
